Focus on your problem zones, your strength, your energy, your flexibility and all the rest. Maybe your chest is flabby or your hips or waist need toning. Also, you should change your program every thirty days. That's the key.

The most important thing in your life is your health and your body. You can have all the education and you can have millions of dollars in the bank, but if you've got headaches every day, if you're fat and you are out of shape - what good is your money? Your health account and your bank account, build them both up!

I'd rather take a beating sometimes than get in that gym every morning. Anyone who gets up that early and says he likes it is a goddamned liar. The only good thing about it is that when I'm finished, I look at myself in the mirror and say, "Jack, you've done it again!

The only way you can hurt the body is not use it.

People don't realize how much of this stuff you get by the end of the day. High blood pressure is from all this high-fat eating. Do you know how many calories are in butter and cheese and ice cream? Would you get your dog up in the morning for a cup of coffee and a donut? Probably millions of Americans got up this morning with a cup of coffee, a cigarette and a donut. No wonder they are sick and fouled up.

Twelve to seventeen minutes is plenty on the treadmill--if it's done fast. That's all you need for cardiovascular benefit. You don't need to spend that extra time unless you are over weight and you need to burn off extra calories. Do it vigorously, like somebody is chasing you. You've got to do it hard. Otherwise, if you just take it easy and do it longer, you are spending all that time when you don't need it. Use that extra time with your weights instead.

Forget about what you used to do. Don't make those same mistakes again. Everybody says, "Oh the good old days" - the good old days are right this second! This moment controls the next moment.
